New to outboards, need help

Re: New to outboards, need help

Why is this thing so badly corroded was it in salt water? Have you had it running at all? Sounds like a lot of grief right now.

I live in South Florida so salt water is about everywhere! Bought the boat knowing that the engine doesn't run (that why I got it so cheap).

I replaced the starter so I could check the compression (85, 91,93,93 psi) kinda low isn't it?
I have no spark so maybe looking at a $200 amplifier, or coil...or distributor...or new wires. I just don't know at this point if it is worth spending money on this motor to get it in order or just junk it, save, and buy another (less old) one.
I agree with what you said, VI-Doug, simple is good but finding parts for this motor as the years pass might become complicated & costly. Also how much longer can I expect this one to run even if I get it to start?so many questions

Take it to the scrap metal yard and put some cash in your pocket. I wouldn't spend big bucks on this unless you really want to restore it but the corrosion on this one is bad. I have a 88 with no corrosion. Hard to say anything about the compression right now, if I could I would run it get some sea foam through it.

Re: New to outboards, need help

Is there a common weakest link in the ignition system of this type of motor (Johnson 1972 85HP)? ignition coil, amplifier, distributor etc.. I trying to figure out if the amplifier is still good. How do you test it? This thing cost $200 so I better be sure it is the culprit before I spend that money on a new unit. Even if I don't keep the motor, getting it to start would give it more resale value so I'm willing to give it a shot (hopefully my bank account will survive this mission).
